ProRes RAW not working on iMac Pro

Hello all. I have a late 2017 iMac Pro running Mojave 10.14.6 and with the most current Pro Video Formats installed (2.2.0). For some reason my system will not decode or play any ProRes RAW files, either via the QuickTime player, quicklook or anything else. The odd thing is that at one time it all worked fine. I could quickly preview PRR files in quicklook or import and play them in Adobe Premiere Pro (CC2020). But now I get errors when I attempt to open the files in Finder, QT or PP. The file icons are QT MOV icons instead of the first frame of the file. The actual files are not corrupt. All files are from a DJI X7 camera.

Not sure what I have done to change anything or cause this to happen. Any ideas or insights would be greatly appreciated. Thank you!
